POWER-TRANSMITTING PLANT.

Specification of Letters Patent.

Patented Apr. 8, 1913.

Original application fll'ed Aifgust' 1, 1911, Serial No. 641,842.. Divided and this application filed February 15, 191a Serial No. 677,837. c

5 tain new and useful Improvements in Power-Transmitting Plants, of which the following is a specification. v

This invention relates to improvements in motors, this application being divided from an application filed by me on August 1, 1911, Serial No. 641,842.

The object of the invention is'to provide means for converting sliding and rotary motion of a plurality of angular pistons into eflicient power.

The invention also comprehends improvements 1n the specific construction and arrangement of parts, which will be herein after described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1- bolted together at 4. Eachsection is formed with semi circular recesses disposed on opposite sides ofthe center, and which form cylindrical openings 3, when the two sections are bolted together. Mounted to rotate in the circular -openings 3, are cylindrical elements 2 and 2. The cylindrical element 2, is formed with a plurality of bores 2 arranged around'a central opening 5,. The bores in the cylindrical elements 2 and 2' correspond to the bores 20 and 20' in the-headsland 1'. 1 I

A cranked shaft -7, fits in the central openings ,5 and 5 in the cylindrical element 2 and the head 1, whereby'td form's, support jor the element 2. Fitting in the bores 20 in head 1, and the bores 2" in the cylindrical element 2, are hollow angular pistons 20* which communicate withpor'ts 50, in the end of head 1; Located to rotate in a casing 9, fitted against the head 1, is a valve 8, formed w1th an inlet port 51, which communicates with an inlet duct 18,

and also formed in the valve is an outlet port 52, which communicates with an out-- rotary motion for producing economical and 1, is a rotor, 4, formed in sections andw an tie 1a duct 19. The v31; 8,18 splined at 7 to the horizontal arm of the crank shaft 7 whereby to cause the valve to rotate with the rotor 4. I

Operating in thebores 3' in the cylindrical element 2' and the bores 20'- in head 1' are the'ends of hollow angular pistons 54. Pipes, indicated conventionally at p 10, 11

and 17, communicate with the bores 20, in

the head 1* and lead to cylinders 12, 13 and 14. Operating in each cylinder is a iston 15, connected by a pitman 56, wit a crank shaft 57. The bores 3, angular pistons 54, pipes 10, 11, and 17, and the cylin ders contain fluid which operates the pistons 15, when the angular pistons 54 are operated, as will be described later on.

In operation, motive fluid enters the duct 18, an thence passes through the ports 51, in registry with the several angular pistons which act as drivers, the upperpiston20 being in position to accomplish this result.

The motive fluid passes through the hollow pistons and contacts with the end walls of the bores in the cylindrical element 2. Pressure of the fluid is then against the two angular surfaces of the angular pistons, in di rection of the arrows on and z. This pressure tends to 'force the pistons out of the bores 20 in the head 1, in the direction of the arrow 2, and thereby rotates the cylindrical element 2. The pressure ofv the fluid between the inner end of the, bores i'n'the cylindrical element 2, and against the horizontal surface of ,the angular pistons 20*, in direction of the arrow :0, serves toforce the pistons out of the bores of said cylindrical element, while the latter isrotating in the cylindrical opening 3. When the angular pistons are reci roca-ted, they not only rotate the cylindrlcal element in the cylindrical opening, but they alsoimpart a rotary motion to said element 2 around the hori-' zontal axis of the rotor 4, consequently the latter is also revolved. When the cylindri cal. element has made one half of a revolution, the orts 50 are shut off from the ports 51, an said orts 50 register with. the Sorts 52, and the aid exhausts through the not 19, when the pistons are returned to their normal retracted position in the bores. While the rotor 4, .is rotating the cylindricalelem'ent 2' is rotating wit it and the glular pistons 54 are operated in substanythe same manner as the angular pisment 2 is revolvel in the opening 3'.

- pistons 15, by the movement of the angular pistons to drive the crank shaft, while the pistons 15 force the fluid back through the angular pistons when exhausting from the cylinders 12, etc. The motive fluid operating through the medium of the angular piS- tons 2O rotates the cylindrical element 2, in its opening 3 and at the same time the rotor 4 is revolved. By this construction, the head 1, in which. the bores are formed, remains stationary and the rotary. motion of the element 2 and rotor 4, will cause the pistons to freely pass each other in their reciprocation in the bores.

, Obviously, by providing the cylinders 0PT.

erat-mg'in conjunction with the crank' shaft 57 the power derived from the rotor may be; transmitted to operate suitable mechanlsm.

What I claim is 1. In an apparatus of "the class described,-

- having a plurality of bores corresponding to the number of bores in'the bearing, hollow angularpistons'having their ends operating in the bores in the head andcylindrical element, a valve having inlet and outlet portswhlch communicate with the ports in the head, means for supplying motive fluid to the inlet portsto operate on the angular pistons and rotate. the, cylindrical element in its opening and to rotate the rotor, the motive fluid being exhausted from the angular pistons through the outlet sports.

2. In an apparatus of the class described, the combinatlon of a rotor, stationary bearings at opposite ends of the rotor, one of said bearingshaving a plurality of longitudinal bores with ports communicating therewith, a plurality of angular pistons operating in the bores, means carried bythe rotor with which the angular pistons cooperate to rotate the rotor, means for admitting motive fluid to the bores to operate the angular pistons, and means to permit the exhaust of the motive fluid from the bores.

3. In an apparatus of the class described, the combination of a rotor having a cylindrical opening, bearings at opposite ends of said rotor, a cylindrical element mounted in the cylindrica-l'opening, one of said bearings having a plurality of bores with communicat-ing ports, the cylindrical element having a plurality of bores corresponding to the number of bores in the bearing, hollow angular pistons having theiriends operating in the bores in the head and cylindrical element, a valve having inlet and outlet ports which communicate with the tive fluid to the inlet ports to operate on the angular pistons and rotate the cylin-- drical element in its opening and to rotate the rotor, the motive fluid being exhausted from the angular pistons through the outlet ports, a second, cylindrical element mounted in the rotor, said second mentioned cylindrical element having bores, the adjacent bearing having bores corresponding to the bores in the second mentioned cylindrical element, angular hollow pistons fitting in the' bores in the second mentioned cylindrical element and the adjacent bearing, a pipe communicating with each bore in the adja cent bearing, a cylinder connected to each pipe, a reciprocating piston in each cylinder, a crank shaft and a pitman connecting the pistons and the crank shaft, the pipes and bores in the second mentioned cylindrical element having fluid which operates the pistons in the cylinders when the angular pistons are operated.

In testimony whereof I have hereunto set my hand in presence of two witnesses.
